This invention relates to governor control mechanisms, and 1s,

governor as adapted to gas engines. The control mechanisms nowemployed1n connection with the hit-and-miss 'type gova hit-and-miss, balanced,two-weight type siredto adjust or enablea quick change of reach over oraround the fly-wheelito unlock a locking device whichholds a governor"With this arrangement adjustment set. v many a ccidents have occurredand n several cases the operators of these gas engines have lost theirhands while attempting to change the adjustment of these governors or ito release the locking device so that the speed that may be regulatedwhile the engine is inof the gas engine-might be varied; Because ofthesenumerous accidents, the Government'now requires that the gasengines be enclosed in a cage, and that the-engine be stoppedbefore anyregulation of the gov-- ernor may be. effected or' thelocking devicereleased so that the speed of'the gas engine may be changed. It isobviously disadvantageous to try to regulate the speed.

. ofthese gas engines when the same are idle. Therefore, an object ofthis nvention 1s to provide a governor control mechanism motion from apoint distant thereto.

An object of this inventionmay' be to provide a'means of control of ahit-and-miss governor which'is effectively and "easily operated at apoint d st'antjfrom a gas enme. g A further object of thisinvention isto provide a means of setting and locking the adjustment of these'hit-and-mlss governors at a point distant from the gas engine.

Other objectsand advantages willbe ap-,

A gasengine is diagrammatically illustrated at 1, having a fly wheel 2adapted to 5, to 1 which gear 5 connected in a manner well known inthedrive a hit-and-miss type governor 3, by

means of a gear 4, wh ch gear-4e meshes with v a governor'zgear 05 apair of balanced weightsfi are pivoted and 7 art so that with anincrease in speed of the fly-wheel 2 the weights 6'are thrown out-Vwarda gainst the tension of a spring 7; A governor'actuating cam 8 is.adapted to slide radially outward ina groove 9in the gear 5 when thebalanced weights, 6'arethrown radially from thecenter by an increasedrate of speed of the fly wheel 2. The cam member 8 is adapted to engagea pick lever roller 10, which pick lever roller '10 is jour naledon asuitable pin '10,which pin 10 is secured to one .end of a pick lever 1l.The

pivoted to a pivoted arm 12,

ing the. connecting rod 17 as illustrated in Fig. 3 and when thecam'member 8 strikes the pick lever-roller 10,.the-end of the pick lever:11 1s thrown upwardfina manner "to. cause the end'1 3 to'be thrustdownward to engage anabutment 1 4 insuch a manneras to hold the'exhaustvalve 15 open so. that the. gas engine 1 will not draw an explosive,

charge of mixture into the cylinder and willfail to fire.

V 7 This operation is well understood inthe art and it is notdeemed'neces- 7 sary to further describe this action, as this inventionrelates toameans for adjusting the position of the roller pinin relationto the cam member 8; it being, of course, understood that the cam-16operates toopen the exhaust 15 through asuitable connect- 'ing rod 317,and that a suitable pressure member 29 acts toreleasethe pick lever '11from engagement with the abutment 14 when the cam member 8 fails toengage the pick lever roller 10 due to the engine slow ing down.

The positionof the pick lever roller 10 is. regulated in relation to thecam 8 by the following means: 7 f

An actuating arm 18 pivotally supported as illustrated at 21 is providedwith an arcuate slot'l9 at its lower end, in which slot 19 a pin isadapted to ride, and which pin 20 is secured to the upper end of the arm12. The lowest point ofthe slot 19' is at the end of the slotnearest thepivot point of the arm 12 so that as the slot 19 is rotated in onedirection, the end of the arm 12 carrying the pin 20 is raised and whenthe slot 19 is rotated: in the opposite direction the same end of thearm 12 is lowered.

on a pin 10" is by this means raised; or lowered so that the cam membersstrikes the roller 10iat intervals depending on the position of theroller 10 lates the speed of the engine '1. Near the upper end of thearm 18 a rod 22' is pivoted as illustrated at 528, and which arm' 22extends outward from the engine 1 and'is adapted to slide'in a bracket23,

7 It will be obvious that by moving the rod 22, o the height of the picklever roller 10 will be varied'so that the speed otthe gas 7 front ofthe engine 1, thereby speed of the gas engine .gas engine 1 is actuatingengine may be regulated. 1

In order to provide a permanent adjust ment of speed, I prefer toprovide a locl-:- ing means, as illustrated at 2 1, to holdthe rgd 22 inpermanent set position when the which locking means is illustrated ascomprlsing a screw clamp 27 and a hand screw 28.

It is often "desirable, especially in .the

case where these gas engines are used in connection with oil wellequipment, to have a connection whereby the speed of the engine may bequickly varied at a point distant to the'en'gine, For this purpose Iprefer to provide a cable 25, one end of which may be extended into theoil well rig, and the other end of which may be provided with a suitableweight 26, the weight haust valve,

The roller 10 being mounted on, the lever 11 which is'pivoted tothe arm12 and thereby regu a well pump,

my invention is for the scope of the appended claims. v
